I mananged to solve the problem with the Gremlin alerts. As well as the now cleaner array, it turned out to be a missing form for my title page shich was giving the 'windows cannot be under forms' alert-see earlier post and I think the other problem was due to a form being reloaded when switching back to the main program from a menu function. In my opinion it is well worthwile trying to get an app running smoothly under gremlins as it can turn up things-which probably not technically bugs or things which stop your app running smoothly in normal testing on the Emulator and Simulator-may cause unforseen problems in the future. Also, I tested the app with Gremlins on several ROMs.
